Description

COMPOSITIONS NON-AQUEOUS LIQUID DETERGENTS, CONTAINING PARTICLES THAT INCLUDE A SURFACTANT OF ALKYLBENCENSULPHONATE FIELD OF THE INVENTION This invention relates to liquid laundry detergent products which are non-aqueous in nature and which are in the form of stable dispersions of particulate material such as blantjueo agents and / or other auxiliaries of the detergent composition. tea.

BACKGROUND OF THE INVENTION Commonly, the use of liquid detergent products is considered more convenient than particulate or powder detergent products. Therefore, liquid detergents have long been used by consumers. Said liquid detergent products are easily measurable, quickly dissolve in the wash water, are capable of being easily applied in concentrated solutions or dispersions to soiled areas on garments that will be washed and do not create dust. They also normally occupy less storage space than granulated products. Additionally, liquefied detergents may have incorporated in their formulations materials that could not support the drying operations without deterioration, operations that are commonly used in the manufacture of detergent products in particles or g nullified- *. Although liquid detergents have a number < The advantages over granular detergent products also have several disadvantages. In particular *, the components of the detergent composition which may be compatible with each other in the granulated products may tend to interact or react with each other in a liquid environment and especially an aqueous liquid environment. In this way, components such as enzymes, surfactants, perfumes, brighteners, solvents and especially bleaches and activators and bleaching can be * especially difficult to incorporate * in liquid detergent products that have a degree of esti-1. 1ad acceptable chemistry. One approach to increasing the chemical compatibility of the components of the detergent composition in liquid detergent products has been that of formulating liquid non-aqueous (or anhydrous) detergent compositions. In said non-aqueous products, at least a part of the components of the solid detergent composition normally tend to remain soluble in the liquid product and are therefore less reactive with each other, than if they had been released in the liquid matrix. . Non-aqueous liquid detergent compositions, including those containing reactive materials such as peroxy ono bleaching agents. they have been described for example in, Hepworth et al., U.S. No. 4,615,820, issued October 17, 1986; Chultz et al., patent of F.U.A. No. 4,929,380, issued May 29, 1990; Schultz and others, patent of E.U.A. No. 5,008,031, issued April 16, 1991; Eider * et al., EP-A-030,096, published on August 10, 1901; Hall et al., UO 92/09670, published June 11, 1992 and Sandersson et al., EP-A-565, 017, published October 13, 1993. Although the chemical compatibility of the components can be increased in the liquid non-aqueous detergent compositions, the physical stability of said compositions can become a problem. This is because there is a tendency for such products to separate in phases as drops of solid insoluble particles dispersed from the suspension and settle to the bottom of the container containing the liquid detergent product. As a consequence of this type of problem, there may also be difficulties associated with incorporating sufficient types and adequate amounts of surfactant materials into non-aqueous liquid detergent products. The surfactant materials must, of course, be selected to be suitable for imparting an acceptable fabric cleaning performance to said compositions., but the use of such materials should not lead to an unacceptable degree of phase separation of the composition. Phase stabilizers, such as thickeners or viscosity control agents, should be added to these products to improve the physical properties of the same. However, said materials can add cost and bulk to the product without contributing to the washing / cleaning performance of said detergent compositions. It is also possible to select surfactant systems for said liquid laundry detergent products that can actually impart a structure to the liquid phase of the product and thus promote the suspension of the particulate components disposed within said structured liquid phase. An example of such a product with a structured surfactant system is found in van der Hoeven and others; patent of E.U.A. No. 5,389,284, issued February 14, 1995, which uses a system of surfactant surfactant based on relatively high concentrations of nonionic surfactants of aleoxi alcohol and ammonium deflocculating agents. In products employing a structured surfactant system, the liquid phase must be sufficiently viscous to prevent sedimentation and phase separation of the suspended particulate material, but not so viscous that the Emptying and dispensability of the detergent product will be adversely affected. According to the above, there is clearly a continuing need to identify and provide detergent compositions containing particles and liquids in the form of non-aqueous liquid products having a high degree of chemical stability, e.g., blantjueador and enzyme, together with a stability of commercial phase AoeptabLe, emptying capacity and performance of blan «cleaning, cleaning or washing of the composition 5 detergent. Accordingly, it is an object of the present invention to provide liquid detergent products which contain particulate and non-aqueous detergents which have such particularly desirable characteristics of chemical and physical stability, as well as a surprising pouring capacity and characteristics of LU washing and bleaching performance. of fabrics.
